The Active Ingredient Is: Tribulus Terrestris

Tribulus Terrestris is an herb often used in supplements to back up hormonal pathways tied to athletic performance, and the ingredient here is standardised for a high protodioscin content, which helps explain its long-standing role as a supplement component.

This blend also contains minerals and other botanicals, which help sustain the overall makeup of the mix and its intended physiological part.

What Does Tribulus Terrestris Do?

Tribulus Terrestris is involved in mechanisms that are described as stimulating androgen receptors and increasing the level of free testosterone in some research contexts, and this information aligns with the product’s stated purpose of supporting training intensity and lean-mass goals.

This product is not intended to diagnose, treat, cure, or prevent any disease.
